Separation of orchid seedlings in the original pot

The Qurans think: the Spring Equinox Mojian, the Autumn Equinox Chunhui. This is a historic summary. Under normal circumstances, the Autumn Equinox changes the basin, which enables Lan Hui to grow better in accordance with the law. The Autumn Equinox's first ten days and the next ten days is the best time to divide the basin. In view of this year's global heat effect, autumn tigers are rampant, and it is reasonable to divide the basin within 20 days after the Autumn Equinox.

one。 Science divides the basin. The quality of dividing the basin is directly related to the survival and growth of Lanhui, so we should not take it lightly. Five to seven days before the split, the mother fertilizer should be applied once, so as to make Lanhui full of vitality and speed up the recovery of growth. When dividing the basin, the basin should be slightly dry to prevent injury to the new roots and blue sprouts. Bud. In the process of operation, do not pull hard, need to use the palm to tap both sides of the basin wall, in order to basin mud (blue stone) shell.

two。 Clean up and disinfect. After Lanhui gets out of the pot, slowly shake off the plants around the orchid root; use sterilized orchid shears to clean the residual roots and leaves; divide the orchid into three to five seedlings and rinse them in tap water. Soak for half an hour in a disinfectant such as carbendazim or methyl topiramate, which is 800 times of carbendazim. Rinse in clean water. Leave it in a cool and ventilated place to dry for 1 to 2 hours. After the root is pale, coat the charcoal ash or sulfur powder with the cut of Lanhui to prevent infection.

three。 Potting skills. Orchid in the basin is like a living room, paying attention to comfort and comfort. According to the number of seedlings, choose the size of the basin. Style, should not be large seedling small basin, especially avoid small seedling large basin; straight bucket basin can put orchid in the middle of the basin, male grass slightly to the side, orchid root upright into the basin; open basin to turn the long orchid root in the basin wall, in order to stabilize the foundation of orchid seedlings. After the plant material is put away, gently shake the orchid basin, so that the orchid root has a slight contact with the plant material.

four。 Sub-management. When is the best time to pour the head water after Lanhui split the basin, there have always been different opinions. I think it depends on the actual situation, if the plant material has some humidity, then slow the seedling for three or four days, and then pour the head water is more conducive to the recovery of Lanhui incision, avoiding the worry of rotten buds. Newly planted Lanhui also does not need to spray water to ensure a smooth transition. In a cool and ventilated environment, it takes seven to ten days to recuperate, and then go to the orchid rack to transfer to normal management.

Especially for high-grade seedlings, in order to reduce the risk and improve the survival rate and seedling rate, it is a good way to take the original pelvis separation operation. The premise is that the old seedling must have roots.

One. Cut with a sharp knife. The method is to remove the covering soil on the false bulb and find the joint between the two pseudo-bulbs to cut accurately.

Two. Disconnect directly with both hands. This method is applied to the old grass with wide road. To master the degree of force in the operation, do not break the false bulb.

Three. After the operation, the dissection can be smeared with thiophanate methyl, carbendazim and other fungicides. Special plant wound ointment also has methyl thiophanate, chlorothalonil, daconine, streptomycin, carbendazim and other powders.

Four. The old grass after the operation does not need to be managed separately, and it can sprout in about 20 days to 1 month.
